Let me tell you my situation. I have made a simple library/module which I can popupulate in my controller. This way I can use one view file and have different results just by changing some of the $form fields(like text inputs, selects, etc). The example is below:
$form = new FormHelper('Webshop bewerken','shop/update',$errors);
$form->addHiddenInput('id',$id);
$form->addTextInput('name','Naam',$item->name);
$form->addTextInput('export','Uitvoer',$item->output_location);
$form->addTextInput('method','Methode',$item->method);
$form->addSidebar();
$form->generateForm();
//show the page
$this->layout->content = View::make('item')->with('form',$form);
The problem exist not within the form. This works fine until i need to validate. However the $errors is undefined so i cannot render the errors.
I have noticed that this variable is only available in the view and not in the controller.
This is fine if you have just a few blade.php files but not in my case(many many screens with generic information).
How can I access the $errors variable (output from the laravel validator) in a controller and not view?
Below is a validator code example i use:
//run the validator
$validator = Validator::make(Input::all(), $rules);
if ($validator->fails()) {
return Redirect::back()->withInput()->withErrors($validator);
} else {
//do something else(not relevant)
}
In your controller you may use:
$validator = Validator::make(Input::all(), $rules);
$errors = $validator->errors();
This will give you the same errors that you get in the view. To access a particular error you may use:
$error = $validator->errors('someFormFieldName')->first();

I have a form that using ajax for update data client. In that form there is an input file. Everything is going fine except for updating the file. File is sent, it changed on storage too, but it gives error on validation and didn't change data on database.
Here is the code on the controller :
public function update(Request $request, Client $client)
{
$validatedData = Validator::make($request->all(), [
'name' => 'required|max:255',
'logo'=> 'image|file|max:100',
'level' => 'required|max:1'
]);
$validatedData['user_id'] = auth()->user()->id;
if ($validatedData->fails()){
return response()->json($validatedData->errors());
} else {
if($request->file('logo')){
if($request->oldLogo){
Storage::delete($request->oldLogo);
}
$validatedData['logo'] = $request->file('logo')->store('logo-clients');
}
$validateFix = $validatedData->validate();
Client::where('id', $client->id)->update($validateFix);
return response()->json([
'success' => 'Success!'
]);
}
}
It gives error on line :
$validatedData['logo'] = $request->file('logo')->store('logo-clients');
With message :
"Cannot use object of type Illuminate\Validation\Validator as array"
I use the same code that works on another case, the difference is the other not using ajax or I didn't use Validator::make on file input. I guess it's just wrong syntax but I don't really know where and what it is.
To retrieve the validated input of a Validator, use the validated() function like so:
$validated = $validator->validated();
Docs:
https://laravel.com/docs/9.x/validation#manually-creating-validators
https://laravel.com/api/9.x/Illuminate/Contracts/Validation/Validator.html
$validatedData is an object of type Illuminate\Validation\Validator.
I would say the error is earlier there as well as this line should give an error also:
$validatedData['user_id'] = auth()->user()->id;
As ericmp said, you first need to retrieve the validateddata to an array and then work with it.
I'm trying to use the Laravel validator to include some custom error messages before I run the validate() method. However it appears that running this method then removed any previously added errors.
I can confirm that the error message appears when I dump out the validator messages before hitting validate()
$validator = Validator::make(
$this->data,
$this->rules
);
$validator->errors()->add('meal', 'The meal field is required.');
$validator->validate();
How I can validate my data but still include the error relating to the meal?
I believe what you want to use is the after validation hook. This will allow you to add more errors like so:
$validator = Validator::make(
$this->data,
$this->rules
);
$validator->after(function ($validator) {
$validator->errors()->add(
'field', 'Something is wrong with this field!'
);
});
$validator->validate();
I have very big problem.
When I submit my form with data everything goes well, but when I won't fill one field in my form laravel throw error MethodNotAllowedHttpException in RouteCollection.php line 218
I have validation in my controller but it does not change anything. When the form is empty it throws an error.
Somebody has a solution for this error?
In your route for this form post use veriables as optional. Use ? In your route definition.
/{var?}/{var2?}/......
From laravel docs-
Occasionally you may need to specify a route parameter, but make the presence of that route parameter optional. You may do so by placing a ? mark after the parameter name. Make sure to give the route's corresponding variable a default value:
Route::get('user/{name?}', function ($name = null) {
return $name;
});
Route::get('user/{name?}', function ($name = 'John') {
return $name;
});
or
// validate the info, create rules for the inputs
$rules = array('data_rozpoczecia' => 'required', 'data_zakonczenia' => 'required');
// run the validation rules on the inputs from the form
$validator = Validator::make($request->all(), $rules);
if ($validator->fails()) { return redirect()->back(); } else{ //do what you want. }
I tried googling and saw other questions posted at this forum but could not find any solution for my issue. I am using Jquery ajaxForm method to submit form. My form contains one file field too in the form that can be used to upload a picture. I have defined the validation in my model. But the issue is even i am uploading a correct jpg file, still i am getting error message that
Argument 1 passed to Illuminate\\Validation\\Factory::make() must be of the type array, object given.
Javascript Code
$('#create_form').ajaxForm({
dataType:'JSON',
success: function(response){
alert(response);
}
}).submit();
Controllder Code
if ($file = Input::file('picture')) {
$validator = Validator::make($file, User::$file_rules);
if ($validator->fails()) {
$messages = $validator->messages();
foreach ($messages->all(':message') as $message) {
echo $message; exit;
}
return Response::json(array('message'=>$response, 'status'=>'failure'));
} else {
// do rest
}
}
Model Code
public static $file_rules = array(
'picture' => 'required|max:2048|mimes:jpeg,jpg,bmp,png,gif'
);
POST Request
I know that my validation defined in the model expects an array. But by passing $file in the validator, an object is passed. Then i changed the code like:
$validator = Validator::make(array('picture' => $file->getClientOriginalName()), User::$file_rules);
Now i am getting error:
The picture must be a file of type: jpg, JPEG, png,gif.
The problem is you pass file object directly to validate. Validator::make() method takes all four parameters as array. Moreover, you need to pass the whole file object as value so that Validator can validate mime type, size, etc. That's why your code should be like that.
$input = array('picture' => Input::file('picture'));
$validator = Validator::make($input, User::$file_rules);
if ($validator->fails()) {
$messages = $validator->messages();
foreach ($messages->all(':message') as $message) {
echo $message; exit;
}
return Response::json(array('message'=>$response, 'status'=>'failure'));
} else {
// do rest
}
Hope it will be useful for you.
Try rule like this.
$rules = array(
'picture' => 'image|mimes:jpeg,jpg,bmp,png,gif'
);
or try removing 'mimes'

Help mi solve this problem
You can't just say 'validate my whole form'.
The reason this error occurs is because you are trying to use the validation method from Laravel.
Basic Form Validation in Laravel
First you want to grab all your form data/content.
$input = Input::all();
Secondly you can setup some rules. Those rules can be set in an array which Laravel will use.
Make sure the names are correctly spelled. (Those are the ones u used in your form-template.)
$rules = array(
'real_name' => 'Required|Min:3|Max:80|Alpha',
'email' => 'Required|Between:3,64|Email|Unique:users',
'age' => 'Integer|Min:18',
'password' =>'Required|AlphaNum|Between:4,8|Confirmed',
'password_confirmation'=>'Required|AlphaNum|Between:4,8'
);
To make use of the validator you have to create anew instance first:
You attach the form input and the rules you have set above.
When they match you can save your form to your database or what else you would like to do with it. That will probably look like:
$validator = Validator::make($input,$rules);
Cool,
We can check now if the Validator passes or not...
if($validator->fails()){
$messages = $validator->messages();
return Redirect::to('yourpage')->withErrors($messages);
}else{
// Handle your data...
}
